Hi, I’ve been looking for a while now in the forum, but can’t get it to work.
Basically I set my data using
this.storage.set('data', [
{id:1, name: 'a'}, {id: 2, name:'b'}
])
How do I edit the name of id:2 without overwriting the array? I’ve done some get and set but end up overwriting the entire object.
Hopefully I got some help. thanks.
Simple solution with Array#Map:
const array = [{ id: 1, name: 'a' }, { id: 2, name: 'b' }];
const result = array.map(x => x.id === 2 ? ({ ...x, name: 'new name' }) : x);
You can’t, not without rearranging the structure. You would have to store each little object under a separate key in order to do that.
I got it to work with
this.storage.get('data').then(valueStr => {
let value = valueStr;
// Modify just that property
value[1].name = "hahaha"; <--- need to specify index
// Save the entire data again
this.storage.set('pets', value);
console.log(valueStr)
});
